RAILWAY-RAIL JOINT.

Specification of Letters Patent.

Patented Feb. 23, 1915.

.application filed July 27, 1914. Serial No. 853,385.

T0 all whom t may concern Be it known that l, ABRAM DRIEDGER, residing at the village of Osier, in the Prov ince of Saskatchewan, Dominion of Canada, have invented certain new and useful Improvements in Railway-Fail Joints, of which the following is a specification.

My invention relates to improvements in joints for railway-rails; the object being to provide means whereby the abutting ends of the rails may be readily and disconnectibly connected without the use of bolts or iish plates of the ordinary type.

Certain other objects of the invention will appear in the description following, and the means by which they are attained will be particularly pointed out in the claims.

Referring to the drawings, which form a part thereof, in which similar characters of reference refer to similar parts throughout the different views, Figure 1 is a view in perspective of a railjoint embodying my invention. Fig. 2 is a cross section of Fig. 1 on the line AB. Fig. 3 is a longitudinal sectional view on the line (J-D 4of Fig. 1. Fig. 4 is an edge view of a locking key as used on each side of the rails. Fig. 5 is a sectional view of a locking key showing a slight modification of the'construction shown in Fig. 4. Fig. 6 is a cross section similar to Fig. 2 but showing the locking keys of a somewhat different shape to allow of their having a bearing against the undersides of the anges on the sides of head of the rail. The rails l and 2 are provided on each side adjacent their ends with longitudinally extending channels 3 and 4, the webs 5 and 6 of the rails 1 and 2, respectively forming the inner sides of the channels depending lianges 7 forming the outer sides of the channels 3 under the heads 8 of the rails, and the inner edges of the raised members 9 formed on the upper sides of the base flanges 10 of the rails, forming the outer sides of the channel 4. The depending flanges 7 on each side of the rail heads 8 it will be noted are integrally formed parts thereof, as are the raised members 9 of the base iiange 10 and it is preferable that the lengths of each of these members apportioned to each end of each rail should be approximately equal. The joining members consist of the keys or joint-plates 11 adapted to be placed in the channels 3 andl 4, but being somewhat longer than the said channels, and having a head 12 at one end and being reduced in thickness somewhat toward their opposite ends to render them springy beyond the end of the channels. On each side of the web 6 of the rail 2 are shown the projecting stops 13 having abrupt faces 14 standing at right angles to the direction of the web 6 and sloping faces 15 directed toward the joint 16 between the abutting ends of the rails 1 and 2. The joint-plates 11 are formed with a sunken portion 17 sloping back to the bottom` of the projection 18 forming a hook 19 thence sloping sharply back to the point 2O of the joint plate most distant from the head 12. To form a connection the rails are placed in alinement end to end and one of the joint plates 11 slippedv into each of thev channels 3 and 4 on either side of the web 5 on the rail 1. As the upper and lower edges of the plates 11 fit the channels 3 and 4 on both rails no difficulty will be found in sliding the plates in the channels until the projecting points 18 ofthe hook 19 strike the inclined plane 15, when a sharp blow with a hammer upon the heads 12 of the plates 11, assisted by the flexibility of the plates as previously mentioned, will cause the points 18 of the hooks 19 to pass over the inclines 15 to lock securely against the abrupt faces 14 of the stops 13. Thus the ends of the rails 1 and 2 have been securely locked together by a plate on either side and without the use of any bolts whatever. When it is desired to disconnect them the point of a crow bar is inserted between the points 2O of the plates 11 and the web 6 of the rail and the hook 19 pried back from the stop 13 when the plate 11 is easily removed in reverse order by a sharp outdriving blow on the projecting head 12.

In Figs. 4 and 5 an addition 21 to the thickness of the plate 11 is shown, the upper and lower vedges 22 and 23 of which are adapted to engage the under surface of the flanges 7 and the upper surfaces of the members 9 respectively and add to the stability of the rail-joint formed.

It will be noted that while the stops 13 for ease in illustration have been shown both upon the rail 2, and on the end of it, and that the plates 11 would both be entered into the channels 3 and 4 in the same direction, it might be preferable that one of these stops be placed at each end of each rail, in which case the plates would enter in opposite directions, and all of the rails carrying the device would then be interchangeable end for end.

By reference to Fig. 3 it will be seen that the ends of the rails 1 and 2 are shown with an opening 16 between them, while the head l2 oi' the plate 11 is in Contact with the ends of the member 9 and the hook 19 in contact with the face 14 'of the stop 13, thus provision is made for the longitudinal contraction and expansion of the rails while movement in all other directions is provided against.

Having thus fully described my said invention vvhat I claim as new and desire to secure by Letters Patent is 1. A rail-way rail joint comprising rails having flanges positioned to form channels under their heads and above their baselanges and stops on the webs of the rails; joint-plates adapted to engage said channels and extend across the meeting ends of the rails, heads on the plates adapted to engage the ends of the flanges on one rail and hooks on the plates to engage the stops on the other rails.

2. A rail-way rail joint comprising rails having flanges positioned to form channels under their heads and above their baselanges and stops on the Webs of the rails; joint-plates adapted to slidably enter said channels, heads on the joint-plates to engage the ends of the flanges on one rail and restrict the movement of said joint-plates in said channels, hooks on the joint-plates to engage said stops and longitudinal ribs on the plates adapted to engage the edges of said flanges.

3. A rail-way rail joint comprising rails having longitudinal channels below their heads and above their base-flanges and stops on their web portions; joint-plates adapted to engage in said channels and extend across the meeting ends of the rails, said joint plates each having means limiting its entrance into the channels on one rail and a latch to engage the stop on the other rail.

et. A rail-way rail joint comprising rails having flanges below their heads and above their base-lianges to form channels between said flanges and the webs of the rails, adjacent the ends thereof, and projecting stops transversely placed on their web portions; a joint-plate adapted to engage in said channels and extend across the meeting ends ol the rails, a head on one end of said jointplate adapted to engage the ends of the `flanges on the one rail and a hook on the other end of said joint-plate adapted to engage the stop on the other rail.

5. A railway-rail joint comprising rails having flanges below their heads and above their base-flanges to form channels between said flanges and the webs of the rails and having projecting stops transversely placed on their web portions; joint-plates adapted to slidably enter said channels and extend across the meeting ends of the rails, heads on said joint-plates adapted to engage the ends oi' the flanges on one rail and latches adapted to engage the stops on the other rail, the relative positions and dimensions of the parts allowing the rails to slide by contraction and expansion.

In testimony whereof, I affix my signature in the presence of two witnesses.
